On Wednesday the 15th of April, VBS4 went to a wind energy workshop. First we went by bus to the Vienna Energy power plant in the 22nd district. Next a man took us to a room where we learned about how to produce energy and why we need renewable energy. After that, two girls aged between 20-25 years old lead us to Mr Power. He introduced himself to us. Next we played some games. They were pretty fun. After that the class went out with Mr Power and he showed us a rotor blade (from a windmill). It lay flat on the ground. We needed to run around it and run as fast as we could. Then we had to stretch our our arms to see if we were longer than the blade altogether. Finally we drove back to school.
